PERM UTATlON-PADLOCK.

SPECIFICATION forming part of Letters Patent No. 585,013, dated June 22,1897.

" Application filed October 16, 1896- Serial No. 609,099. (No model.)

To all whom it may concern.-

Be it known that I, THEODORE R. VINZENT, of Salem, in the county ofMarion and State of Oregon, have invented a new and ImprovedPermutation-Padlock, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedpermutation-padlock which is simple and durable in construction, cheapto manufacture, and arranged to enable the owner to readily change thecombination to prevent unauthorized persons from tampering with thelock.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described herein after and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a perspective view of the improvement. Fig. 2 is a sectionalside elevation of the same. Fig. 3 is a face View of one of thetumblers. FigS-" L is a cross-section of the improvement on the line 4 4of Fig. 2.

Fig. 5 is a side elevation of the several tumblers, and Fig. 6 is abroken perspective view of the bolt.

The improved padlock is provided with two heads A and B, provided withbars A B, respectively, of which the bar B has a reduced end B adaptedto engage a correspondinglyshaped socket A formed in the end of theother bar A. From the head A extends parallel to the arm A a sleeve 0,the free end of which abuts on the head B and the said sleeve is adaptedto be engaged by a bolt D, projecting from this end of the head B.

The bolt D is provided with a number of lugs D D D placed suitabledistances apart and adapted to pass through a longitudinal slot O,formed in the sleeve Q, and into transverse recesses (3 ,0 0respectively formed in the said sleeve, as indicated in Fig. 2. When thelugs D D D register with the said recesses O O 0 then the bolt D ispartly withdrawn from the sleeve 0 andthe reduced end B of the bar B isthen out of the socket A to permitof turning the head B, so as t openthe bars A and B.

On the sleeve O are mounted to turn the on a shell H, mounted to turn atone end on an offset A formed on the head A, and at its 0, the saidcollar being formed with recesses 1, adapted to be engaged by pins Bprojecting from the head B for locking the latter against turning. Thekey H is. adapted to engage, with the end proj ecting beyond the innerface of the tumbler E, the end F of a bar F held in one of the recessesF formed on the periphery of the tumbler F. The bar F is adapted to beinserted in .any one of the recesses F according to the desiredcombination, and the bar is held in place in the corresponding recessesby a spring F in the shape of an open ring, fitted into an annulargroove F formed at or near the middle of the tumbler F. The bar F hasits other end F projecting beyond the other face of the tumbler F, asshown in Fig. 5, and this end F is adapted to engage the end G of a barG held in one of a series of longitudinal recesses G formed in the thirdtumbler G". A spring G serves to hold the bar G in place in thecorresponding recess G Each of the tumblers E F G is formed at its borewith a recess E for the passage of the lugs D D D of the bolt D, so thatthe bolt D cannot be withdrawn from the sleeve 0 unless the recesses'E?in the several tumblers registerwith the longitudinal slot C of thesleeve 0. The face of each of the tumblers is marked or graduated,preferably as indicated in Figs. 3 and 4-, a numeral being for eachslot, so as tdihdicatethe location of the corresponding bar F or Grelatively to the tumblers F and G and the key H relatively to thetumbler E.

It is evident that by the arrangement described the operator can set thekey H to engage the desired numbered recess E in the tumblers E, F, andG, separated from each other by collars O secured on the said sleeve Thetumbler E is formed in its periphery with longitudinal slots E, one ofwhich is; adapted to be engaged by a key I-I,'formed other end on acollar 1, screwing on the sleevetumbler E, so that the turning of theshell II causes the key 11 to turn the tumbler until its recess E is inalinement with the slot 0'. As the key II is also in the path of theend. F of the bar F it finally moves into engagement with the said endto turn the tumbler F until the latter is brought in position with itsnotch registering with the slot 0. As the other end F of the bar I?" isadapted to engage the end G of the bar G the tumbler G is turned untilits notch comes in register with the slot C. Of course the tumblers canonly be turned into these positions if a person knows the combination atwhich the padlock is set, and when the several tumblers are in thisposition the head B can be moved outward, so as to disengage the reducedend B from the socket A and permit of turning the head IS, with the boltD as the spindle, so as to completely open up the bars A and B. Theoutward sliding motion of the head B with the bolt D is limited by thefirst lug D abutting against the inner face of the collar I.

It will be seen that by the arrangement described the owner of thepadlock can readily change the combination whenever desired, so as toprevent unauthorized persons from tampering with the lock. The shell IIis formed at one outer end with a graduation II, reading off on a markformed on the head A, so as to enable the operator to readily turn theshell II to bring the several tumblers into the proper position foropening the lock, as above described.

Having thus fully described myinvention, I claim as new and desire tosecure by Letters Patent 1.
